Title: Dam water level control system
Inventor: SAITO TERUAKI
IPC: G05D9/12
Filed: 1987-07-01
Abstract: PURPOSE:To attain rapid and stable control independently of the size of a reservoir area by correcting a water level deviation due to the inflow volume of water into a dam. CONSTITUTION:A water level Hu measured by a water gauge 3 on a water measuring bank 2 arranged on the upstream of the dam is transmitted to a dam water level control device and upstream inflow Q'i found out by a previously applied river flow formula is set up as a main control value. A water level deviation DELTAH between a dam water level HL measured by a water gauge 4 and a previously set reference water level Hs is calculated and a correcting value is found out from a flow rate set up corresponding to the deviation DELTAH. The main control value is added to the correcting value to set up the added value as a control value and discharge volume Qo is controlled so that the water level is kept at a fixed level. Thereby, an error between the inflow Q'i and real inflow Qi coincides with the deviation DELTAH of the water level and the control value reaches to the inflow Qi.

Title: Ink jet recording head
Inventor: MIURA MASAHIKO
IPC: B41J2/105
Filed: 1985-07-23
Abstract: PURPOSE:To eliminate the occurrence of dispersion of ink discharge characteristics by unformly controlling the meniscus of ink formed on plural ink discharge ports. CONSTITUTION:The width of flow path in an air layer 14 to which air stream coming out of one of air discharge ports 1- n becomes D (where D is the arranging pitch of ink discharge port 2- n or air discharge port 1- n. The smaller the pitch D becomes, the narrower is the flow path and the faster is flow rate in the flow path. It follows thus that pressure loss occurs in the air layer 14. Air pressure Pn in near the ink discharge port 2- n is lowered beyond air pressure Pa in the air chamber 3. In the case drop of 0.02kg/cm<2> or less, ink pressures between the outside and inside of the ink discharge port can be easily balanced with the pressures of ink by controlling the levels of liquid at the ink discharge port and in the ink tank. As a result, the discharge characteristics of ink from each ink discharge port can be uniformly controlled, and a multi- nozzle head having less dispersion in the discharge characteristics can be obtained.

IPC: G06T3/40
Filed: 1990-06-21
Abstract: PURPOSE:To ensure the high display quality with no deterioration of the image of the original image data by applying the logical arithmetic processing to the results of conversion obtained by the 1st and 2nd conversion means and therefore correcting the variance of variable power magnification produced in both conversion means. CONSTITUTION:A 1st conversion means 1 magnifies the image data alternately and variably in (n + 1)/2 and (n - 1)/2 times respectively. A 2nd conversion means 2 magnifies the image data alternately and variably in (n - 1)/2 and (n + 1)/2 times respectively. Therefore the picture element data is always magnified in (n + 1)1/2 times by one of both means 1 and 2 and then in (n - 1)/1 times by the other means as long as one of those picture element data forming the image data is noted. Then the conversion data generating means 3 and 4 apply the logical arithmetic processing to the picture data which are variably magnified by both means 1 and 2. Thus the variance of variable power magnification produced by both means 1 and 2 can be corrected. As a result, the conversion image data are produced without deteriorating the image of the original image data.

Abstract: PURPOSE:To accelerate the shift of the specified speeds at starting and stopping time by forming to include a counter in a pulse generator for varying the speed of a motor and enabling to set the output pulse width in response a load amount. CONSTITUTION:An acceleration pulse generator 7 is operated by a signal from a terminal 8, a capstan motor 4 for a VTR is rotated by the output, and a pulse signal proportional ro the speed of a rotation detector 5 is supplied to the generator 7.
